Pressure independent control valves (PICVs) help pumps run slower and minimize the energy consumption of hydronics systems
When you’re managing a large/high-rise building where the temperature variances make some areas too cold and others too hot, you know the frustration that comes from trying to keep tenants comfortable without driving your energy consumption levels through the roof.
Pressure independent control valves (PICVs) – a type of balancing valve – provide better temperature control, save energy by running your pumps slower, and prevent over-pumping your system when compared with conventional, manual control valves.
PICVs Offer Precise, Efficient Flow Control
PICVs combine the functionality of two valves in a single part. The valves – which can be used in a variety of hydronics systems – eliminate the need for separate control and balancing valves. Instead, PICVs combine both operations in one unit to precisely adjust to fluctuations in flow pressure.
The hybrid functionality of PICVs allow them to save hydronics systems from over- or under-pumping. When your pumps run at 50% speed, your energy consumption and costs are reduced by 88%. You will also get better control of energy sucking boilers and chillers because your entire hydronics system will run at the designed delta T.
The integrated control valve with flow limitation automatically provides more or less flow through the valve depending on the selected actuator.
For the Gold Standard in PICVs, Trust Danfoss
Danfoss, a forward-thinking engineering company that manufactures a variety of sustainable indoor climate solutions, is the leading global manufacturer of PICVs. The company’s pioneering Danfoss AB-QMä PICVs are the gold standard in pressure independent control valves. The AB-QM provides 100% valve authority, so room temperature always meets the set temperature.
The unique benefits of Danfoss AB-QM PICVs are unmatched in the indoor climate control industry, and include:
- More stable and comfortable room temperature
- Cost and energy savings
- Reduced maintenance costs
- Easy installation
Several imitators have attempted to replicate Danfoss’ design but fall far short. While most are less expensive than the AB-QM upfront, they do not offer the same long-term cost savings and do not regulate temperature as consistently.
One Valve, Multiple Applications
Danfoss AB-QM PICVs are available in sizes ranging from ½” to 10”. The diversity of sizes and unique design of the valves makes installation less complicated than conventional control valves. And, because the right fit PICV is based on flow requirements, no Cv calculations or sizing considerations are required.
The valves can be used to make a variety of heating and cooling systems run more efficiently. These include, but are not limited to:
- Air handling units
- Fan coil units
